Revisiting static ice storage in clinical lung transplantation: Direct and continuous temperature monitoring of donor lungs followed by mathematical modeling.
Article in JHLT open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: In clinical lung transplantation (LTx), direct and continuous measurement of donor lung temperature under static ice storage has rarely been reported. Although assumed to be 4°C, recent studies suggest temperatures may approach 0°C. This study aimed to establish direct, continuous monitoring of lung temperature, fit temperature changes to a mathematical model, and evaluate their association with clinical outcomes. Methods: This prospective single-center study included clinical LTx cases between July 2024 and January 2025. Direct temperature monitoring at the end of preservation ( Results: Median end-of-preservation temperatures were 8.6°C (range: 1.21-13.35°C) at the surface and 5.3°C (0.15-12.10°C) at the interlobar region, but intercase variability was observed. Nevertheless, temperature curves generally remained above freezing. Interlobar curves showed better model fitting than surface curves (median R-squared: 0.98 vs 0.95). The >4°C interlobar group demonstrated significantly better primary graft dysfunction grades post-LTx ( Conclusions: Direct measurement showed lungs preserved on ice generally remained above 0°C, but freezing injury could not be completely ruled out. Interlobar temperature more closely followed the model, reflecting lung temperature dynamics. Interlobar temperature >4°C was associated with better graft function.
